摘要 把语法分析和Ontology结合起来 ,先利用领域Ontology里的概念、关系、关键字自动生成标注规则(Rule) ,然后对文章、句子的语法结构进行分析 ,再利用语法分析的结果和先前生成的标注规则一起对文档进行信息标注与抽取 。 Use the concepts,relations and keywords of domain Ontology to generate information annotation rule automatically and then do grammar parsing on the document.After that we combine the result of grammar parsing and information annotation rule to do information annotation and extraction on document and at last output the result as a list of records
